I make 29k a year in my estimate, it'll end up being less due to being casual and not being paid holidays, public holidays, time off for my son (who has ASD) apps and both kids sickness. But as I get full rate, this won't change come tax time.
Child support is assessed as being 5k a year.
Rent is $20,540 a year ($395/week).
I'd get an additional $409.08/fortnight if I were an Australian Resident. Which is more than I've had taken off me since becoming single, but it still doesn't justify reduced payments for FTB-A and RA.
